Keenan, You should cut that thing down!  Ha, ha.  I wish I could get permission to cut Crabapple in a local swamp--I'd be set for life.  
Thanks Oldbow!  I've been working hard on my grips.  I think it's one of the most difficult parts to keep natural looking.
Timber Wolfe, I'm not sure there is a difference.  I've studied what my tree books say about Crabapple and it seems that Pacific/Oregon are used interchangeably.  I have another Crabapple bow I made from a very clean stave that draws about 90# @ 28" and I've pulled it a lot further than that.  It's great wood.  Look for the cleanest, straightest, stave you can find and it will last forever.
Phil,  What an honor to have a picture in someone else's shop.  By 'thorn apple' do you mean, Osage or Hedgeapple?  Crabapple is also called 'thorn apple' and 'ironwood' in some areas but I don't know if what you have is the same thing.  If it's any of those things, however, it should make a great bow.  Your density test is more than good news, too.  Let us know what happens.
WIBOWYER, Thanks a lot.  It's a definite 'worst case' stave.
